Description

Large Blade Share Web Lifting Apparatus

The present invention relates to a large blade shear web lifting device, and more particularly, to a large blade shear web lifting device capable of stably absorbing and safely and quickly transporting large, heavy parts having flat or curved surfaces.

Typically, lifting and transport devices are used to manufacture large parts and transport them to the next process or a specific location.

Traditionally, to transport large parts, a lifting device was connected to the large part using a sling belt. This approach required additional work to connect the sling belt to the large part and the lifting device, which resulted in significant time and labor costs for transporting large parts.

Accordingly, lifting and transport devices are being developed in various ways, including an electromagnet lifting device that uses an electromagnet to fix and transport parts, and a vacuum suction type lifting device that transports parts by suction using a suction pad.

In particular, as wind turbine blades grow larger, the components they incorporate are also becoming heavier and larger. Shared web components inserted into the blade's interior are removed from the mold and lifted for transport to the next process after molding is complete.

The present invention discloses a technology capable of safely transporting a share web inserted into the internal space of a blade among large parts.

The suction detection sensor may detect when the part (20) falls from the large blade shear web lifting device (100) or is not suctioned when the large blade shear web lifting device (100) attempts to transport the part (20), and transmit the detection to the control device.

Meanwhile, in the present invention, the large blade share web lifting device (100) is typically used to transport the share web of a large blade, but is not limited thereto and is described as being capable of transporting any large part (20).

Below, the configuration of the large blade share web lifting device (100) is described in detail.

FIG. 2 is a front view illustrating a large blade share web lifting device according to one embodiment of the present invention, and FIG. 3 is a side view illustrating a large blade share web lifting device according to one embodiment of the present invention.

As illustrated in FIGS. 2 and 3, a large blade share web lifting device (100) according to one embodiment of the present invention may include a lift body (110), an adsorption member (120), and a vacuum pump (130).

The lift body (110) can be connected to a crane wire (10) connected to a crane. The lift body (110) can include a first body (111) and a second body (112).

The first main body (111) may have an internal space (1111) formed and a cross-section formed approximately in the shape of the letter ㄷ. A vacuum pump (130) may be positioned in the internal space (1111) of the first main body (111). The first main body (111) may surround the periphery of the vacuum pump (130) positioned in the internal space (1111) and protect the vacuum pump (130) from external obstacles.

The first body (111) may further include a wire fixing hole (1112) and an anti-rotation stopper (1113). The first body (111) may include at least one wire fixing hole (1112) and an anti-rotation stopper (1113).

The first body (111) can be coupled to the upper surface of the second body (112). In one embodiment, the first body (111) can be formed as an elastic structure whose height and width can be adjusted according to the size of the vacuum pump (130).

The second main body (112) can be connected to the first main body (111). The second main body (112) can have a cross-section formed in the shape of the letter ㅡ. A vacuum pump (130) can be installed on the upper surface of the second main body (112), and an adsorption member (120) can be coupled to each of one end and the other end.

Meanwhile, in this embodiment, the lift body (110) is described as being separated into a first body (111) and a second body (112), but this is not intended to be limited thereto, and it may be formed as a single body, or it may be formed in various shapes not shown in the drawing as long as it has the same configuration and function.

The lift body (110) according to the present embodiment may include at least one of a length adjustment member (213), a first rotation adjustment member (214), and a second rotation adjustment member (215).

Referring to Fig. 4, the length adjustment member (213) can be installed on the second main body (212). The length adjustment member (213) can be installed close to the suction member (120) coupled to each of one end and the other end of the second main body (212) to adjust the position of the suction member (120).

The length-adjusting member (213) can be expanded and contracted in the longitudinal direction of the second body (212) according to the size of the component (20), and the position of the suction member (120) can be adjusted according to the expansion length. For example, the length-adjusting member (213) can be an expandable device such as a linear motor or an air cylinder.

Referring to Fig. 5, the first rotation control member (214) is installed in the second body (212) and can rotate in the first direction. Here, the second body (212) is separated into the 21st body (2121) and the 22nd body (2122), and the 21st body (2121) and the 22nd body (2122) can be connected by the first rotation control member (214) installed between the 21st body (2121) and the 22nd body (2122).

That is, each of the 21st main body (2121) and the 22nd main body (2122) can rotate around the first rotation adjustment member (214) to adjust the angle of the suction member (120) coupled to each end. Here, the first direction in which the 21st main body (2121) and the 22nd main body (2122) rotate can be the front-back direction in the front direction of the large blade share web lifting device (100) illustrated in FIG. 2.

Referring to Fig. 6, the second rotation control member (215) is installed in the second main body (212) and can rotate in a second direction perpendicular to the first direction. Here, the second main body (212) is separated into a 21st main body (2121) and a 22nd main body (2122), and the 21st main body (2121) and the 22nd main body (2122) can be connected by the second rotation control member (215) installed between the 21st main body (2121) and the 22nd main body (2122).

That is, each of the 21st main body (2121) and the 22nd main body (2122) can rotate around the second rotation adjustment member (215) to adjust the vertical height of the suction member (120) coupled to each end. Here, the second direction in which the 21st main body (2121) and the 22nd main body (2122) rotate can be the vertical direction in the front direction of the large blade share web lifting device (100) illustrated in FIG. 2.

In this embodiment, the lift body (110) includes at least one of a length adjustment member (213), a first rotation adjustment member (214), and a second rotation adjustment member (215), so that the angle and position of the suction member (120) can be adjusted to suction a large part (30) having a curved surface as shown in FIG. 9 in addition to a flat large part (20).

Referring again to FIGS. 2 and 3, the adsorption member (120) can be coupled to one end and the other end of the second body (112), respectively. The adsorption member (120) is connected to a vacuum pump (130) and can adsorb a large component (20) by vacuum pressure transmitted from the vacuum pump (130).

The adsorption member (120) may include a height adjustment member (121), an adsorption plate (122), and an adsorption adjustment unit (123).

The height adjustment member (121) can be installed at each of one end and the other end of the second body (112). The height adjustment member (121) can be adjusted so that the suction plate (122) and the suction adjustment part (123) move away from the second body (112) or so that the suction plate (122) and the suction adjustment part (123) move closer to the second body (112).

In one embodiment, the height adjustment member (121) can automatically adjust its height according to the gap between the second body (112) and the component (20) so that the component (20) can be adsorbed by the adsorption member (120). This can be usefully used when the position of the large blade share web lifting device (100) is restricted by external obstacles, etc.

In the drawing, the height adjustment member (121) is depicted as being composed of bolts and nuts, but it is not intended to be limited thereto, and any device capable of adjusting the height of the suction member (120), such as a linear motor or air cylinder, is possible.

The suction plate (122) can be coupled to one end of the height adjustment member (121). The suction plate (122) has a trapezoidal cross-section, and an suction adjustment unit (123) can be installed inside. In one embodiment, a filter (not shown) can be installed on the suction plate (122). The filter can filter out external foreign substances to prevent external foreign substances from entering the interior of the vacuum pump (130) when the vacuum pump (130) is operating.

The suction control unit (123) can have one end connected to a vacuum pump (130) and the other end connected to an suction plate (122). When the suction control unit (123) sucks air from the vacuum pump (130), a vacuum suction force is generated, thereby suctioning the component (20).

Referring to Fig. 7, the suction control unit (123) may include a plurality of suction blocks (1231). The plurality of suction blocks (1231) may each be independently coupled to the suction plate (122). The plurality of suction blocks (1231) may be coupled to the suction plate (122) to have a certain elasticity so that shock that may occur when adsorbing a component (20) is not transmitted to the lift body (110).

At least one of the plurality of suction blocks (1231) may protrude from the inside to the outside of the suction plate (122). For example, if the joint surface of the large component (20) is uneven, some of the plurality of suction blocks (1231) may protrude downward to correspond to the uneven surface and adhere to the joint surface of the large component (20).

Referring to Fig. 8, the suction member (120) may further include a third rotation adjustment member (224). The third rotation adjustment member (224) may be coupled between the height adjustment member (121) and the suction plate (122). The third rotation adjustment member (224) may connect the height adjustment member (121) and the suction plate (122) so that the suction plate (122) can rotate 360 degrees around the height adjustment member (121).

In this embodiment, the suction member (120) can be angle-adjusted to absorb a large part (30) having a curved surface as shown in FIG. 9 in addition to a flat large part (20) including a third rotation adjustment member (224).

Meanwhile, although not shown in the drawing, the adsorption member (120) is connected to the vacuum pump (130) through a separate connection pipe, and may include other known devices for providing vacuum adsorption force to the adsorption control unit (123), and a detailed description thereof is omitted.

Referring again to FIGS. 2 and 3, the vacuum pump (130) may be installed in the second body (112) so as to be positioned in the internal space (1111) of the first body (111). The vacuum pump (130) may be connected to the suction member (120) to provide vacuum suction force to the suction member (120).

The vacuum pump (130) can generate a vacuum suction force in the suction member (120) by sucking air from a connecting pipe connected to the suction member (120). Here, a power source for driving the vacuum pump (130) can be configured separately.

FIG. 9 is a state diagram showing a state in which a part is lifted by suction using a large blade share web lifting device according to a modified embodiment of the present invention.

As illustrated in FIG. 9, the large blade share web lifting device (200) further includes at least one of a length adjusting member (213), a first rotation adjusting member (214), a second rotation adjusting member (215), and a third rotation adjusting member (224), so as to adjust the angle and position of the suction member (120) so as to suction a large part (30) having a curved surface in addition to the flat large part (20) illustrated in FIG. 1.

An adsorption control valve (340) may be installed between the lift body (310) and the adsorption member (320). The adsorption control valve (340) may be opened and closed by a control device (not shown). The adsorption control valve (340) may selectively transmit the vacuum adsorption force generated by the vacuum pump (330) to the adsorption member (320) depending on the opening and closing.

The adsorption control valve (340) may be installed at the front end of the adsorption member (320) corresponding to each adsorption member (320). That is, the adsorption control valve (340) may be installed in a connecting pipe connecting the vacuum pump (330) and the adsorption member (320) to control the flow of air flowing through the connecting pipe.

According to this embodiment, the large blade share web lifting device (300) selectively provides vacuum suction force to the suction member (320) according to the opening and closing of the suction control valve (340), thereby enabling the component (20) to be flexibly suctioned by the suction member (320) according to the size of the component (20).

In this embodiment, at least one of the length adjustment member (213), the first rotation adjustment member (214), the second rotation adjustment member (215), and the third rotation adjustment member (224) described above may be further included so as to be able to absorb a part (30) having a curved surface.
